RD52.1-4B-011-L-V1-FW

The Bosch Rexroth Indramat RD52.1-4B-011-L-V1-FW from the RD 500 Drive Controllers offers precision AC drive control with a Nominal Connecting Voltage: 3 x AC 380-480 V and a Rated Power: 11 kW rating. This unit is designed as a Unit Type: Converter with a built-in brake chopper, ensuring dynamic braking capability without additional hardware. A robust Cooling Mode: forced air cooling system maintains thermal stability under continuous operation. With its compact footprint and industrial-grade build, the RD52.1-4B-011-L-V1-FW is ready for demanding automation tasks.

The drive’s intelligence extends to a fault memory: 10 faults (S0–S9) that logs errors in chronological order, with S0 holding the most recent event and S9 the oldest. An integrated LED display provides visual status—green for ready and red for fault—while menu-driven prompts on the user panel guide parameterization. Access to sensitive settings is protected by a multi-level password system, and the supply voltage can be toggled via the onboard S5 jumper. Connection integrity is enforced: the motor must be wired through the X2 interface and the encoder via the manufacturer’s dedicated cable.

Commissioning is streamlined by a built-in copy function that replicates configuration across multiple controls, reducing setup time in large installations. An internal relay with two positively driven contacts enables safe logic integration, and the use of AL electrolytic capacitors as DC link storage ensures stable bus performance. Backed by a one-year support agreement and shipped through a global logistics network, the RD52.1-4B-011-L-V1-FW embodies reliability and ease of integration for modern drive applications.
